OF NEW ZEALAND. 389 



Elytra a little broader than the base of the thorax, narrowed 

 behind, with about fifteen striae on each, these are rather fine, and those 

 between the seventh and three marginal ones are more or less irregular, 

 they are finely punctured, but seem confluent and indistinct near the 

 apex, which is somewhat rugosely punctate, the interstices are almost 

 flat, punctulated, sometimes with only one row of fine punctures on 

 each. 



Ufider-side bronzed, not very glossy, punctate, with short greyish 

 hairs proceeding from the punctures ; prosternal process moderately 

 narrow, margined, slightly convex, and projecting a little beyond the 

 coxse ; tnesosternal process wide raised sides. 



The second joint of the antennce is shorter than the fourth, the third 

 distinctly shorter than the fourth and fifth conjointly, the last larger than 

 tenth, obtusely rounded. 



The insect is shining, and nearly nude above. 



Length, 4-4§ lines; breadth, i|-2. 



Allied to A. zealandiciem, but with the punctation of the thorax 

 more remote, with distinctly punctured elytral strife, much more distinct 

 rims to the thorax and elytra, and with the thoracic disc compressed a 

 little at the sides, so as to leave a depression near the side margin. 



Sent from Otago recently by Professor Hutton. 



692. A. lentum, n.s. Of a brownish-bronze colour above, with 

 reddish legs and antennse, the former darker ; it is oblong, sub-parallel, 

 attenuated posteriorly, the thorax and elytra of almost equal width, and 

 the latter relatively short. 



Head short, immersed up to the eyes, curvedly narrowed towards 

 the front ; epistovie short and broad, emarginate in front, with a puncti- 

 form impression near each side, its suture slightly curved; forehead 

 somewhat flattened, moderately and not closely punctured. Prothorax 

 sub-quadrate, moderately convex, emarginated in front with obtuse 

 slightly depressed front angles, the sides sub-parallel, a little rounded 

 anteriorly ; base almost truncate, with a small triangular excision in the 

 middle not large enough to render the scutellum visible ; it overlaps the 

 elytra, is rather densely and finely punctured, with a large elongate 

 basal depression midway between the middle and side, another near 

 each side in line with the middle, and two less obvious ones on the 

 dorsal line, all rather shallow. Elytra short, a good deal narrowed 

 behind, with about seven rows on each of rather fine yet quite distinct 

 punctures, which, however, become obsolete in line with the hind 

 femora, the outer quite indistinct, and their whole surface more or less 

 finely and closely punctured. Under-surface punctulated, and darker 

 than the upper. 



Femora rather inflated, the tibiae and tarsi with yellow hairs. The 

 third joint of the antenna; shorter than fourth and fifth taken together. 



Length, 3^ lines ; breadth, nearly ih. 



The insect seems rather broad in front, the thorax being only slightly 

 narrowed posteriorly gives it a peculiarly parallel outline to beyond the 

 middle of the elytra; the apex of the thorax is not deeply emarginated.
